What transformation does Ditto use to appear human in Pokémon Pokopia?

Ditto uses its Transform ability to appear human in Pokémon Pokopia.

The game’s central premise depends on Ditto changing form. After discovering an old Pokédex connected to its trainer, Ditto assumes a human-like appearance and uses that form while rebuilding the abandoned Kanto environment.

In the wider Pokémon series, Transform is Ditto’s signature move and allows it to copy another Pokémon’s appearance, moves, and other battle characteristics. Pokopia adapts that familiar concept into a story and gameplay tool rather than presenting Ditto only as a battle participant.

Imposter is a different term associated with Ditto’s Hidden Ability in some Pokémon games, but it is not the answer to the question about the transformation used in Pokopia’s premise. Dynamax and Terastallization are battle-related mechanics from other Pokémon settings.
